"A year after revealing a major upgrade of the BlackBerry Enterprise Server was underway, Research in Motion this week finally fleshed out what the new version will do, and put a delivery date on it...
The BES (pronounced 'bez') is the locus of an enterprise BlackBerry deployment. All communications funnel through the BES, it works with the back-end mail servers Exchange or Lotus Notes, and provides some tools for administering and managing BlackBerry devices, users, and the BES itself.

For that to happen, enterprise BlackBerry administrators need to move visibility into the BES. They also need tools to simplify and automate deploying and managing scores of mobile applications, including line of business programs. Finally, they need improvements in BES to make it more reliable and scaleable if it's to be the linchpin for mission critical mobile business and communications."
